DELIVERY APPARATUS FOR CONFECTIONERY MACHINES.

To all whom it may concern Be it known that I, ALoNzo LINTON Bans- MAN, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Deli-very Apparatus for Confectionery Machines, of which the following is a specification.

This invention relates to delivery apparatus for confectionery machines and has particular reference to an apparatus designed to receive the candies fromthe'machine, convey them through a cooling apparatus and thence to packing stations or any other point of delivery.

The apparatus is particularly applicable to a standard type of chocolate coating niachine, receiving the freshly coated candies on a belt by means of which they are conveyed through a suitable cooling device and the coatings hardened, and affording means for loosening the hardened candies from such belt and conveyingthem past operators who piclr up the candies and. paclr them or, if desired, delivering the candies into trays to be otherwise and later packed.

The object of the invention is to'provide an apparatus of the class described embodying certain advantageous arrangements of parts and improved constructiona. features, as will more particularly appear in the following description and. in the illustrative embodiment of the invention in the accompanying drawings, in which Figs. 1 1*, 1, and 1 taken together end to end show a complete plan view of the apparatus, certain parts of this view being shown in section;

Figs. 2 2*, 2, and 2, taken together end to end show a complete side elevational view of the apparatus,certain parts of this view being also shown in section; and

Fig. 3 is a cross-sectional view taken on the line 33 of Fig. 1".

Referring to these drawings in detail, A represents a portion of the casing of any suitable candy making machine and this machine may, for example, be a candy coating machine of the general type disclosed in U. S. Letters Patent No. 790,184. granted May 16, 1905, on an invention of Gabriel Carlson. The product of this machine, such as candies coated with chocolate, are caropenings 16 at opposite ends to Application filed. November 10,1922. Serial No. 600,161.

ried on the usual conveyer 0 and by it transferred automatically to a conveyer 10. The latter is usually an endless belt of suitable fabric and may have a special smooth glossy finish to prevent the candies from adhering too tightly thereto or a second belt,

such as 11, of'material, such as oil cloth or the like, may be associated with-it, asillustrated. In any event, the conveyer, whether a single or double one, carries the candies, preferably in continuous fashion, through a casing B, wherein the coatings are cooled, as by currents of cold air which are caused to circulate therein. The cooled candies emerging from casing B are then stripped from the con-veyer by a thin stripper plate 12 and slide down the latter'upon a second conveyor 13, which may be an. ordinary canvas belt. Conveyer 13 is mounted to travel in a frame .6 and between two packing shelves 14 thereon and carries the finished candies within easy reach. of the packers who remove them and pack them in boxes on shelves 14. Or, it it is not desired to thus pack the candies, the conveyer' 13 is arranged to deliver'them into trays 25, which are caused to move from below the conveyer past a chute 15, down which the candies fall into trays t.

The casing otherwise known as a cold box, will first be described. It consists of a relatively long box-lilre structure, having receive the itudinal partition 1? which divides it horizontally into upper and lower compartments 18 and 19, the former accommodatingbelts 10 and 11 in both upper and lower laps of travel and the lower containing the cooling means. Centrally arranged in casing l3 and disposed on opposite sides thereof are vertical conduits 20 by means of which communication is established between the compartments 18 and 19. -At each end of the casing similar conduits 21 are provided for the same purpose. The lower compartment 19 is divided centrally bya vertical partition 22, which extends in a general diagonal direcbelts 10 and 11 and has a lo tion from one side wall of one conduit 20 to the opposite side wall of the other conduit so that one conduit 20 communicates with one half of compartment 19 and. the other conduit 20 with the other half of the compartment. The upper compartment 18 is similarly 'divided by two partitions 23 and 2 1, which are vertically spaced from one another to permit the passage ofthe upper lapof belts 10 and 11 and the lower partition 24 is spaced from the partition 1? fans being tired to a shaft 26 rotatably mounted in and extending transversely across casing B. Cooling coils 27 are provided in each "section of compartment 1.9, in which coils a suitable cooling mediun'i, such as brine or ammonia, may 'be circulated. A

- 'clrip pan 28 is provided in-undcrlying rela- "tIOII WVltll the coils. Each fan' draws air from the'remote end of one compartment 18 through the two vertical conduits 21 into the compartment 19, which is located therebelow and forcesthis air'up through one of the central vertical conduits 20 and back into the-same compartmentw. The air drawn back from compartment 18 travels along the coils 27 and is cooled to the desired degree. 'Ba'fiies 29 are provided in each section of compartment 19 as best shown in Figs. 1 and 3, to cause the air to travel in a sinuous path, thebetter to efiect'its cooling. Each baflie 29-is fastened to a side wall of casing B and is notched,'asat to slip. over one side'of coils 29' and projects into close proximity :to the other side of these coils.

The casing B is preferably provided with double walls, comprising; outer and inner walls 31 and 82, which are spaced apart as shown in Fig. Sand may receive between them'suitable insulating material, indicated at 33. The cover for casing B is preferably made in a similar fashion and consists of a plurality of removable sections whereby access may be had to the interior substantially from end to end thereof to permit assembly of parts therein.

The upper laps of belts l and 11 are supported during their travel through casing B upon a horizontally disposed'table, which extends longitudially of the-casing and mid-- way between-the upper and lower walls of compartment 18. This table is an'ade upof avplural'ity of thinsheetmetal sections 35, which are mounted enduto end inabutting relation and which have :their abutting ends .downturne'd, as at 36 (Fig. 5111' order to eliminate sharp-edges, such; as *might abrade belt 10. These sections- SS'are-supported by and between two laterally spaced wangle airons '37, which extend longitudinally of the casing .in parallel, but preferably delivery end of conveyer 0.

nearly square corner than would at the-end of its upper lap oftravel.

thereof,the angle irons 37 being supported at suitable intervals by. brackets 38, thus leaving openings, as 39, through which communication may be established between the upper and lower portions of compartment 18. Each section 85 is perforated, as at 39', to allow the cold air to pass therethrough from below and reach the under lap of belt .10, the betteriand .more rapidly to cool the bottoms of the confections.

'Inassembling the-parts in casing B, all the work is done from the top,the cover sections 34 being removed. The dripfipan 28 is first laid in place, after which the coils 27 are inserted. Then the baffles 29 are'mounted in place, togetherwith pa'rtition 22and the 'fans,after whiclrpartition 17 is laid in.

deposited on the angle irons as shown. This workis done either before the belts are mounted on, their 'end supports or else while sufficient slack is otherwise. provided for this purpose. The various parts in casing B are mounted in such a fashion as tobe conveniently removable to' permit assembly in the manner described. The covers 34, as heretofore described, are also conveniently removable for the same purpose and also for the purpose of gaining access to the confections when necessary or desired.

The conveyers and 11 are supportedat one end-by a table 40 (Fig. 2) which is pivotally supported at 41 atone end from the casing B and at the other end rests upon a shelf 3 of the'coating ma'chine A, preferably being adjustably supported from such shelf through the intermediary of screws 42. The described arrangement enables the receiving end of conveyers l0 and 11 to be convenientlyaligned withthe he table 40 has a comparatively thin rounded "edge around which the conveyors 1'0 and ll move in passing from their lowerto theinupper laps of travel. Referring now to Fig. 2 the other end of conveyer 10 passes around adriving roll 44 which is rotatablyimounted in a. floor stand D. A small roll45,- also rotatably supported in the latter, is provided to cause the conveyer toturn a more It oth'erwlse If" two belts are used; the beltl'l only"=need travel over roll 45. From 1151144, both belts travel over an idler roll 46 j and thence to a second idler 47 (Fig. 2 downwardly around a roll LSfthence up- Belt 10 extends :wardiy overa roll 47 and thence along the slightly spaced, relation with the side walls partition 17. Belt ll also extends from roll tion delivery apparatus.

46 to roll 47 and thence do vnwardly around a separate roll 49 and then :e upwardly over roll 47, returning along the same path as belt 10. The rolls 4S and 49 constitute separate belt tensioning devices for the belts and 11, respectively. these rolls being suitably mounted, as indicated, for move ment in a general vertical direction and functioning, as by their weight to keep the belts tight. Referring to Fig. 2 the roll 44 carries a worm gear 50 which is driven by a worm 51 fixed .on a shaft 52, rotatably mounted in suitable bearings on a side wall of floor stand. D. Shaft 52 is connected by a universal joint 53 to a shaft 54 which extends, as indicated, back to the coating machine A, being connected by a universal joint 55 to that shaft of such machine which usually drives the ordinary confec- The shaft 54 includes a suitable number of universal joints, as indicated, and is mainly supported by bearings provided on the casing B.

The conveyor 13 is driven from a roll 56 mounted in floor stand D and this ro ll carries a worm 57- which is driven from a worm gear 58 fixed on a shaft 59, rotatably mounted in suitable bearings on one side wall of the floor stand, but below the described shaft 52. The shafts 52 and 59 are connected by any suitable speed changing device so that conveyer 13 may be driven from conveyer 10 but at various relative speeds. Thus, shaft 52 may carry av group of three gears 60. which are slidable on the shaft by means of a shift lever 61. Shaft 59 carries three axially spaced gears 62 of complementary sizes. As shown, the mid dle gear 60 is in mesh with the middle gear 62, whereby czonveyer 13 is driven faster than conveyer 16, but the ears 60 may be shifted to the right to cause the right hand gears 60 and 62 to engage and thereby drive conveyer 13 at slower speed than conveyor 10 or the gears 62 may be shifted to the left to cause the left hand gears 60 and 62 to engage and thereby drive conveyer 13 at the same speed as conveyer 10. Thus, by this speed changing device, the confections may have the same spacing on conveyer 13 as a conveyor 10, or the spacing may be made greater or less, as desired.

The conveyor 13 is supported during its upper lap of travel on a table 64, carrying at one end an idler roll 65 over which the conveyer passes and returns to an idler roll 66. thence passing downwardly to tension roll 67 and thence upwardly to a roll-68, from which it returns to driving roll 56. A roll 69 is provided to cause the conveyer 1.3 to make a comparatively sharp turn in passing to its upper lap of travel. Roll 69 is located adjacent but below roll 44, and the inclined stripper plate 12 bridges the gap between the two conveyers and has an edge lying in close proximity to conveyer 11 as it passes over roll 44. Plate 12 is stationarily supported from the side walls of floor stand D, as indicated. The table 64 has longitudinally disposed angle irons 70 secured to its side edges, which upstand from the table and furnish side guides for conveyer 13. That and of table 64 remote from roll 65 carries two laterally spaced arms 71 which are pivoted at 72 to the floor stand D. The table 64 is otherwise supported by the angle irons 70 resting on brackets 73 fixed to frame (l. Thus, table 64 may be lifted, if necessary, to gain access to partsbelow and it is susceptible to a rising movement without damage should this prove necessary.

The packing shelves 14 are provided with backs 75, between which the table 64 and conveyor 13 is arranged. These backs 75 have openings 76 therein near the delivery end of conveyer 13 and below table 64, through which a tray 2 may be passed and disposed in under the table 64 and con veyer 13. The tray, thus positioned, is supported on two of a series of three rolls 77. The center roll of this series is driven by worm gearing 78 from a shaft 7 9 which is connected to the described shaft 59, whereby it is driven at approximately the same speed as conveyer 13. Thus. the tray t, positioned as described, is moved in the same direction as conveyer 13 and passed outward- 1y beneath the chute 15 to receive the candies delivered upon the latter by the conveyer.

The chute 15 is pivotally supported to swing about an axis concentric with that of roll 65 and can rise and fall to accommodate the outwardly moving tray. The latter eventually engages the outer roll 77 of the series.

which roll is driven by a chain 80 and suitable sprockets from the middle roll of the series. The tray is eventually moved upon idler rolls 81 where it rests until removed by an operator. The rolls 77 and 81 are suitably mounted in bearings provided on the no backs 75.

The operation of the apparatus will sufficiently appear from the foregoing description.
